about special relay due to earthquake from Taiwan

Hi,

We meet the big problem in sending out email to China, Hong Kong and some of
Asia domains. Telecommunications around Asia were severely disrupted on
Wednesday after earthquakes off Taiwan damaged undersea cables, slowing
Internet services and so on. We are trying to relay some mail server to
solve this problems.

I know I can use transport and relay_domains and relay_recipient_maps maps,
but I have another questions, would you please give me a hand?

One of ISP provided the email address for me to forward some domains
messages, and then they will send out these messages automatically. This
seems to be like relay_domains function, but I have checkd the conf(5) in
postfix web site, don't know how to do that.

for example, I assume thess special email address called "
dogz.hkexample.com" for relaying to Hong Kong and "dogz.cnexample.com" for
relaying to China. If my colleagues want to send out the email to Hong Kong
or China and so on ... My server will forward these message to those special
email address.

But how can I set up these to make sure my mail server to decide which mails
should forward to dogz.hkexample.com or dogz.cnexample.com ?

another question is how they handle that messages to send out the mail to
right destination ? If I need to create like this for another office to
use.

Any suggestions will appreciate.

Thank you in advance.
